Frontiers in Microbiology, 2021 Microbial communities are composed of many rare species and a few abundant species. Considering the disproportionate importance of rare species for ecosystem functioning, it is important to understand the mechanisms structuring the rare and abundant ...

Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]
, 2019 Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process
Advanced Engineering Materials, EarlyView.This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...

Ecology and Evolution, 2020 The role of interspecific interactions in structuring low‐diversity helminth communities is a controversial topic in parasite ecology research. Most parasitic communities of fish are species‐poor; thus, interspecific interactions are believed to be ...

Frontiers in Plant Science, 2023 Plant-soil negative feedback (NF) is a well-established phenomenon that, by preventing the dominance of a single species, allows species coexistence and promotes the maintenance of biodiversity. At community scale, localized NF may cause the formation of

Advanced Engineering Materials, EarlyView.Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Coexistence of nearly neutral species [PDF]
Journal of Plant Ecology, 2012 Aims The neutral theory of biodiversity provides a powerful framework for modeling macroecological patterns and interpreting species assemblages. However, there remain several unsolved problems, including the effect of relaxing the assumption of strict neutrality to allow for empirically observed variation in vital rates and the ‘problem of time ...

The Effect of Food Concentration on the Juvenile Somatic Growth Rate of Body Length, Fecundity and the Production of Resting Eggs by Moina brachiata (Crustacea: Cladocera) Single Females [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2012 The study addresses the effect of different food concentrations of green alga Chlorella vulgaris on the life cycle parameters (the body length, specific juvenile somatic growth rate of body length, the number of offspring in the first clutch of ...

An evolutionary model for simple ecosystems
, 1999 In this review some simple models of asexual populations evolving on smooth landscapes are studied. The basic model is based on a cellular automaton, which is analyzed here in the spatial mean-field limit.

Monte Carlo cluster algorithm for fluid phase transitions in highly size-asymmetrical binary mixtures [PDF]
, 2010 Highly size-asymmetrical fluid mixtures arise in a variety of physical contexts, notably in suspensions of colloidal particles to which much smaller particles have been added in the form of polymers or nanoparticles.
